We have a SBS2003 with 4 client machines connected via hard-wired lan with 1 GB Network cards and switch. The server has 1 network card for the LAN and another for the ADSL modem (uses ISA as firewall).
Cients all running Win XP Pro SP3
Initially 2 clients were on the network and running fine. We then added a computer to the network. Initially it was very slow "applying computer settings" before the logon dialog appeared but seems to be normal now. We have just added the 3rd machine and it is doing the same thing but hangs for 20-30 minutes before it displays the logon dialog. When we can eventually get onto the machine it appears to be running on the netwrok ok but any time we do a re-boot this huge delay occurs.
I am a newbie to server and active directory etc so please keep solution in layman's terms if possible. (stpe by step instruction would be ideal).
Any help much appreciated.
